The Marmot sleeping bag called, Trestles 0
is actually EN tested at -3°F / -19°C comfy rating,
and has a -40°F/C survival rating.
This synth bag has incredible loft.
As many have stated on other sites,
the zipper, all be it a very nice zipper,
it is a challenge to operate.
The stuff sack is just adequate,
with a draw cord that is sorely lacking.
The stuff sack compression straps however, are awesome,
and can compress the bag to near ½ its size.
There is a standard and large choice, 6' or 6'6".
Choices include left or right double ended zipper,
with a 1/2 length zipper on the other side.
There is a zippered pocket inside for storage, somewhat small, but there.
Draw cords for the Insulated Collar which has two snaps on each side instead of velcro.
The hood and breast flap have separate draw cords.
The head hood is a very nice touch.
The bag has amble foot room and a decent ankle spread for a mummy.
I have never had an Insulated Collar in a bag,
So I was glad it didn’t seem to be in the way to much,
And will grow to love it in real cold weather.
First test, it was 0°C and I was in a Clark NX150 4 season Jungle Hammock
with Z-Liner and DIY pads to fill hammock pockets.
I wore a cotton short sleeve T shirt, and long sleeve Turtle neck,
Dakota dri wear lower long johns, and standard socks.
In my first test at 0°C or 32°F, I was just over the edge of, to warm.
I didn’t sweat but was very close to it.
Getting into the bag, standing beside the hammock is as easy as any bag,
And then sitting and swinging into the hammock is as all other bags.
Organizing the lay in the bag while in the hammock is also a task,
But no more so than with other bags.
I could feel that the loft under me was much more retained than my other bags.
The loft above was cozy, and the set up did not take long at all to warm.
The time to warm the bag seemed shorter than my other bags,
And I am not sure that is in any way a scientific declaration,
But seemed to warm really fast.
As time goes on I will update this report with colder temps,
I believe that with the setup I have I could easily get down to -30/-35 in comfy mode.
But we'll see . . .
I see a couple of plus's and maybe 1 minus
Plus's are EN rated so you know it is like comparing apples to apples
so when it is held to a down bag they will perform basically equal while sleeping,
if conditions are dry.
Cost at $125 cnd, is totally acceptable compared to a down bag at about $549.
Minus, down is lighter and compresses more . . .
. . . oh well . . . according to the EN testing I can go colder by 2°
for $424 less.
I would say the plus' totally out weighs the minus
Thanks for reading.
